Description Carlos O'Ryan 2002-11-24 16:42:06 CST 
The implementation of the CDR extration operator (>>) for object keys and other
"TAO_opaque" objects is incorrect.  More specifically, it does not take into
account if the source data is zero-copyable.

This bug can result in crashes.  I will submit a patch, so there is no reason
not to get it fixed for 1.3
